I have mySingle topic layout set to “Classic Forum” so that they will look like the forum pages here. But I keep getting a lot of weird visual effects. Im using Divi theme which is a pretty widely used theme, do you have a CSS guide on how to repair visual issues?
I'll take a look at that and I take your point about Divi being a popular theme. It's just not possible to build something that accounts for idiosyncrasies in every theme.
